Foci of bronchopneumonia were found in animals that died several days after exposure and there was evidence of functional disturbances in CNS.
How is brine made?
Raw brine is warmed in a heat exchanger and caused to pass successively through two packed towers by gravity flow. In the upper (smaller) tower, it meets a recycle stream of gases from which chlorine and bromine are absorbed. Near the bottom of the lower tower, chlorine and steam are introduced; as they pass upward, the chlorine reacts with bromide in the brine, and a mixture of bromine vapor and chlorine (about 85:15 by weight) with steam is taken off the top. The water and most of the halogens are condensed, the liquid phases enters a gravity separator and the gas goes to the upper tower. From the separator, water containing dissolved halogens is sent to the lower (steaming-out) tower and the heavier bromine layer, containing some chlorine, flows to a fractionating column. The chlorine vapors join the stream to the upper tower while the liquid bromine, about 99 % pure, is drawn off either for direct use in the manufacture of bromine compounds or to be further purified for sale or for more exacting uses.
